landlab.graph.object.ext.at_node module#

Find links touching a node and their directions.

Parameters
  • node (int) – A node ID.

  • nodes_at_link (ndarray of int, shape (n_links, 2)) – Nodes at link tail and head.

  • links_at_node (ndarray of int, shape (max_links_per_node, )) – Buffer to hold link identifiers for links around node.

  • link_dirs_at_node (ndarray of int, shape (max_links_per_node, )) – Buffer to hold link directions for links around node.

Returns

The number of links found.

Return type

int

Get links touching each node and their directions.

Parameters
  • nodes_at_link (ndarray of int, shape (n_links, 2)) – Node identifiers for each link tail and head.

  • links_at_node (ndarray of int, shape (n_nodes, max_nodes_per_link)) – Buffer to hold link identifiers for each node.

  • link_dirs_at_node (ndarray of int, shape (n_nodes, max_nodes_per_link)) – Buffer to hold link directions for each node.
